As we keep pumping carbon dioxide into the atmosphere, more of it is dissolving in the oceans, leading to drastic changes in the water's chemistry. Triona McGrath researches this process, known as ocean acidification, and in this talk she takes us for a dive into an oceanographer's world. Learn more about how the "evil twin of climate change" is impacting the ocean -- and the life that depends on it.

Triona McGrath: How pollution is changing the ocean's chemistry

How pollution is changing the ocean's chemistry

Ocean acidification, dubbed the 'evil twin of climate change', could increase by 170% by 2100, affecting marine life globally.

A study finds pteropods' shells, vital in the marine food chain, nearly dissolve in future ocean pH levels, hinting at ecosystem collapse.

By 2100, 70% of cold-water corals, crucial for biodiversity and fisheries, face risk from oceans dissolving their structures.
